Abstract

The invention provides a tunnel detector. The detector comprises an antenna box, an elastic telescoping mechanism, a direction adjusting mechanism and a support mechanism, wherein the antenna box is used for filling a radar antenna used for detecting the quality of a tunnel lining; the elastic telescoping mechanism is arranged below the antenna, is connected with the antenna box, and is used for enabling the radar antenna to be always in contact with the surface of the tunnel lining during detecting; the direction adjusting mechanism is arranged below the elastic telescoping mechanism, is connected with the elastic telescoping mechanism, and is used for enabling the radar antenna to angularly rotate so as to detect the different positions of a tunnel; the support mechanism is arranged below the direction adjusting mechanism so as to support the antenna box, the elastic telescoping mechanism and the direction adjusting mechanism. According to the tunnel detector provided by the invention, the radar antenna can be always closely contacted with the surface of the tunnel lining in the process of detecting, so that a detection result is stable; and in addition, the tunnel detection device provided by the invention can detect the different positions, such as the vault, haunch or side wall of the tunnel, and is flexible to adjust, and strong in applicability.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a tunnel detection device. Background technique [0002] At present, in the process of non-destructive testing of the quality of tunnel lining concrete, the loader welds a simple platform or a special vehicle for high-altitude maintenance, and manually lifts or holds the radar antenna close to the lining surface. The strength is high, the detection line is difficult to locate accurately, and the adaptability is poor. Therefore, it is necessary to provide an effective auxiliary device to improve the safety of detection work and the stability of detection results. [0003] In the prior art, the patent publication number is the tunnel vault detection device disclosed by CN 102759754 A, and the tunnel side wall detection device disclosed by the patent publication number CN 102749214 A. The problems of high-altitude operation hazard and high labor intensity in ground radar de...
